The Rockchip SoC rk3288 has 2 types of device trees floating around. A 64bit reg size when synced from Linux and a 32bit for U-boot. A pre-probe function in the syscon class driver assumes only 32bit. For other odd reg structures the regmap must be defined in the individual syscon driver. Store rk3288 platdata in a regmap before pre-probe during bind. Signed-off-by: Johan Jonker <jbx6244@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org> Tested-by: Simon Glass <sjg@chromium.org>
